Who is threatening the preservation of nature on the planet today?

I belive that human activity threatens the preservation of nature on the planet. Excessive affluence in daily life accerates deforestation. As the result, it generates environmental destruction such as water shortage, global warming and so on. I’ll discuss two aspects of this topic.

First, excessively increasing livestock farming. We are in abundant environment that we can easily purchase meet on the market. According to one report, 40% of tropical rain forests in South America were destructed for livestock farming of the exported beef during these 40 years. If we abstain from eating meet, it would be effective to stop the destruction of tropical rain forests. We should a little bit forgo excessively relying on meat industry.

Second, the rapid increase in the number of Slash and burn agriculture in order to produce food. Slash and burn agriculture is particularly important throughout the tropics where, when done properly, it can provide people with a secure source of food and income. Many critics point out however that when done improperly, slash and burn agriculture can quickly degrade large areas of forest which do not recover. We are too much in affluent environment. For example, it is said that 30% of lunch box sold at convenience store are thrown out. What a waste it is! Let’s reduce the variety of lunch box. We should refrain from excessive supply on the market.

We should not forget that we can get affluence in return for environmental destruction.

In conclusion, excessive affluence could deal a significant blow on the preservation of nature on the planet today.

What are the biggest risks to humanity in this century?

The biggest risks to humanity are the risks that have always been there: asteroid strikes could still wipe us out; infectious diseases, either manmade or natural, could still wipe us out. Climate change could now wipe us out; nuclear war could still wipe us out and also nanotechnology could. In order to avoid this and to survive the next 100 years, what should we do? Probably we need to engineer ourselves to be wiser and less aggressive.
Now we are living in era of biotechnology. Some scientific experiments shows that we have possibility to be able to manipulate human genes to make better human beings. And one professor of biology says "If so, why don't we take an action to save our Earth?" Does this still sound a rather radical SF story?
