Many biological species have become extinct in the past and the fossil record suggests that in the past, they have been at times more numerous in species than they are now. Furthermore, the mankind can also be one of the species that will be running for extinction.
Moreover, mankind has had a stronger affect on the rate and nature of extinctions occurring because there are a lot of events by the climate conditions from the global warming. Whereas both theories the destruction of environment by humanity and magnetic North change by movement from the Earth’s core, the first is a situation that we have capacity to change now.
Although changes have been gradual, most but not all scientists agree that climate is getting progressively warmer.
Nevertheless scientists put the blame for this to human activity increasing the amount of carbon dioxide in the atmosphere. Global warming could cause climate change extreme weather conditions in some areas climate change may make it impossible to grow food in some regions. The melting of polar ice and thermal expansion of sea water, can increase sea levels and flooding of lowlands.
The greenhouse effect which is a big problem for mankind because of which every year there is a drastic change in weather conditions and unfortunately we have been watching a lot of news with dead people because a catastrophic event happened.
On the other hand, we will have contributed to our own extinction if we have not had to pay attention in the principal issue from Toronto Conference on the changing atmosphere for twenty years ago.
The mankind’s future depends to continue little attitude in order to protect, safe and rebuild the environment.
