1. Ecology plays an important role in our life. Today, everyone knows what ecology is. Although 100 years ago, few people knew about its meaning. The actual fact is that ecology has acquired special significance in our days, as our planet has become in need of protection from the people themselves and their actions. Unfortunately, the economic revolution has made life easier, bringing many benefits for convenience and luxury, but has caused irreparable damage to our common home.
Now thousands of factories are built, waste and every one garbage are being dumped, and natural resources are being extracted – all this can be making the living conditions on Earth worse and worse a day. What has changed since the times that have already passed, when people didn't consider the environment at all? Why is everyone so concerned about the environment today and constantly discussing various environmental issues? And, in general, is it correct?
It is worth noting that humanity could be a self-regulating mechanism that independently and automatically regulates all the processes that occur in it. the least bit times, humanity has exploited nature, taking from it what they needed from it. But people never returned anything to nature, only using her gifts, but giving nothing reciprocally.
And at a specific moment, at the height of contemporary science, humanity has set itself a rational question: can this exploitation last forever? and other people realized that this brazen use of nature can't last forever. People saw that some species of plants and animals had disappeared from the face of the planet forever.

Also, people realized that the amount of species of living creatures continues to decline sharply. And this is often absolutely not normal. When people realized all this, people began to consider a way to deal with this problem.

It began to make special rules, formulate laws, and even international acts that might protect the environment-animals, plants, and everything else that's so important for the continued existence of the globe. It's impossible to imagine what sad consequences await humanity if the environmental situation continues to deteriorate. It is excellent that individuals have realized how serious the results of neglecting the environment and ignoring these problems may be.
The state supports environmental services that work to restore the environment, decrees and bans are being introduced, and therefore the subject “Ecology” has been introduced in class, at universities so young generation learn to require care of what we've left from an early age. It also offers recycling and recycling of garbage, special filters are being built to purify fumes at industrial enterprises, and environmentally friendly cars are being created that run without fuel and without exhaust gases. It's important to value the environment and take care of it. So the planet won't only be cleaner, but better!
2. The environment plays a major role to support life on earth. But there are some issues that are causing damages to life and also the ecosystem of the world. It's associated with the not only environment but with everyone that lives on the earth. Besides, its main source is pollution, warming, greenhouse emission, and lots of others. The everyday activities of humans are constantly degrading the standard of the environment which ultimately leads to the loss of survival conditions from the planet. There are many issues that causing damage to the environment. But during this, we are visiting discuss the most causes of environmental issues because they're very dangerous to live and therefore the ecosystem.
Pollution – it's one amongst the most causes of an environmental issue because it poisons the air, water, soil, and noise. As we all know that within the past few decades the number of industries have rapidly increased. Most of those wastes contain harmful and poisonous materials that spread very easily due to the movement of water bodies and wind.
Greenhouse Gases – These are the gases that are accountable for the rise within the temperature of the planet surface. These gases directly relate to pollution thanks to the pollution produced by the vehicle and factories which contains a toxic chemical that harms the life and environment of earth.
Climate Changes – because of environmental issues the climate is changing rapidly and things like smog, acid rains are becoming common. Also, the amount of natural calamities is additionally increasing and almost every year there's flood, famine, drought, landslides, earthquakes, and plenty of more calamities are increasing.
And now I want to write down about their effects. For example, the negative effects of global warming:
Sea levels are expected to rise between 10 and 32 inches (26 and 82 centimeters) or higher by the top of the century.
Floods and droughts will become more common. Less water is going to be available, since glaciers store about three-quarters of the world's freshwater. Some diseases will spread, like mosquito-borne malaria (and the 2016 resurgence of the Zika virus).
Ecosystems will still change: Some species will move farther north or become more successful; others, like polar bears, won’t be able to adapt and will become extinct.
Secondly, the negative effects of world climate change:
Global climate change will affect people and also the environment in many ways. a number of these impacts, like stronger hurricanes and severe heat waves, may be life-threatening. Others, like spreading weeds, are going to be less serious. However, because the Earth keeps getting warmer, the negative effects are expected to outweigh the positive ones. The more we find out about how global climate change will affect people and also the environment, the more we are able to see why people have to take action to cut back the gas emissions that are causing temperature change. we are able to also take steps to arrange for the changes we all know are coming.
To conclude, we will say that humans are a serious source of environmental issues. Likewise, our activities are the most important reason that the amount of harmful gases and pollutants have increased within the environment. But now the humans have taken this problem seriously and now working to eradicate it. Above all, if all humans contribute equally to the environment then this issue may be fight backed. The natural balance can another time be restored.
3. The world is losing most of its natural resources and there are many factors that are making this happen, however, one major concern is that of deforestation. Human activities are leading to deforestation at a really rapid rate. Moreover, the consequences of this activity are very dangerous. We don't realize the damage we are causing to living beings in addition because the vegetation by cutting down trees. it'll be clearer if we understand the impact of deforestation and make attempts to stop it.
When we cut down even one tree, the impact is huge. Now imagine if we clear out whole forests only altogether, how damaging would that be. We prevent forests to fulfill the wants of humans. so as to meet the agricultural, commercial, industrial, residential, and other needs we remove forests. Most of the world was covered with forests until 100 years ago, however, now we don’t have much of them left.
Deforestation causes disruption within the ecological balance. Moreover, it also interferes with the lives of wildlife and groups of people further. Firstly, when there won’t be many forests left, the water cycle of the planet will get disturbed. There won’t be enough trees left to soak up the water. Moreover, it'll cause floods and droughts too. Similarly, eating away are going to be another effect of deforestation.
Other than that, the climate will experience massive change. Heating is additionally happening partly because of deforestation only. The oxygen level within the atmosphere will sink by a good number and thus naturally carbonic acid gas levels will increase. Most significantly, the wildlife is losing their habitats because of deforestation. Forests are their only home and with no place left to travel, they either lose their lives or wreak havoc within the cities.

Therefore, we must all move to prevent this from happening and saving our earth additionally as our lives. Humans must not be so selfish so on make other animals homeless to shelter themselves. We must not damage our vegetation to make a good looking garden for ourselves.
