More than two decades ago, scientists warned the world that some human activities such as exploitation of the water supplies, depletion of the ozone layer and destruction of the rain forests, are doing an irreversible damage to the planet.

They also emphasized that the population is continuously growing and the natural environment is being reduced. All these activities will undoubtedly make our planet uninhabited.

Since we haven’t done anything to heed their warnings, scientists have issued ″a second notice″. According to them, as the time passes we have even less time to deal with these problems.

In other words, since we have failed to solve these environmental challenges, everything is getting worse and soon it will be too late to address these issues.

They have also mentioned that when this problem was originally addressed, the planet didn’t have so many people like today and therefore it is much more difficult to do something now than it was 25 years ago.

Specifically, their biggest concerns are:

• Running out of drinkable water
• Massive deforestation
• Increasing pollution
• Dead zones in the oceans
• Destruction of the bio-diverse areas by the industries
• The mass agriculture, etc.

All these concerns are threatening the earth’s and mankind’s future. As a result, scientists assume that by the end of this century, the humanity could be completely extinct.

Another thing that should be taken into consideration is the continuous biological destruction that can affect the ecological, economic and social life.

Due to our behaviors, the world that we know today might be gone soon and the upcoming catastrophe will be caused by human self-destruction.

Scientists also pointed to the lack of measures that were taken after they had made the first warning. Namely, we failed to take actions to limit the population growth and to restore the ecosystem. Apart from stabilizing the hole in the ozone layer, all other threats have worsened.

However, although we don’t have much time, there are still good chances to save the forests, to reduce the usage of chemicals and fuels, to stop the water pollution and downsize the population.

There are many environmentally sustainable alternatives that should be implemented as soon as possible in order to save our planet. For example, we should have fewer kids, eat less meat, use green energy and protect the wildlife reserves.
