Global Warming

The increased human activity on the planet generates greenhouse gases such as water vapor, carbon oxides (COx), nitrous oxides (NOx), methane (CH4), chlorofluorocarbons (CFCs) and other gases, which are increasing the “greenhouse effect” on the planet that leads to global warming.
Global warming increases the average temperature on planet Earth, which melts the glaciers at the pole, and leads to rising sea levels.
Global warming also produces extreme heat during the summer season and extreme cold during the winter.
The extreme heat during the summer can kill many people, produces droughts, which affects crops and animals, and could lead to famine in many countries.

Climate Change

Climate change is another major environmental issue on planet Earth that in the last decades has raised many concerns among scientists over the future of the human civilization on the planet. Raising average temperatures on planet Earth leads to global warming, which is responsible for the change in the climate paths.

Overpopulation

The number of people on the planet increases every year mostly due to the fact that the number of people in the undeveloped or developing countries increases at alarming levels.
The increased number of people on the planet would not be an environmental issue if the natural resources would be unlimited.
Sadly, the technology is not capable today to create more natural resources or to create human colonies on other planets.
Planet Earth has limited resources and if the place gets very crowded, we will face very harsh living conditions.
