The nature reserves play an important role in reducing the amount of carbon dioxide emissions. 15% of the terrestrial carbon sink in the world was stored in nature reserves around the world. In Canada, more than 40 million tons of carbon dioxide being stored in 39 National Park, which’s value is equal to 39-87 billion dollars of carbon credits. In the Brazilian Amazon, about 670,000 square kilometers of the forest will be avoided being degraded in 2050 because of nature reserves. Some natural disasters such as flood, debris flow disaster and storm all can be relieved by nature reserves. It is estimated that 232 billion dollars was saved owing to avoid flood caused by the typhoon in American coastal wetlands every year.

Nature reserves can ensure the health and richness of natural resources, which leads to resist climate change and offers food, clean water, shelter and income for community residents. The drinking water of 33 cities, included in the global biggest 100 cities, are from the stored water in nature reserves.

Veerle Vanderweerd, a NDP Energy and Environment Officer, said the living environment in rural is being threatened by climate change. If there was no immediate action, the living conditions will worsen.

Trevor Sandwith, the vice president of Nature protection association and the IUCN world nature reserve committee said expanding the coverage of nature reserves, in fact, is an effective measure to resist climate change.

Climate negotiations are under discussion in Copenhagen and 2010, the year of international biodiversity, is coming. Expanding the range of nature reserves is an effective weapon to resist climate change.

Bamboo Growth
The main reason behind bamboo’s eco-friendliness is the fact that it is one of the fastest growing plants in the world. Bamboo is actually a type of grass that has been recorded to grow an average of 60 centimeters in one day during its growing season. Some species of bamboo can even grow as much as 121 centimeters in a day. Bamboo poles reach maturity within five years and then decay and die towards their eighth year. At which point, new shoots sprout from the intact root system of the plant. Thus, if harvested between their 3rd and 7th years of growth, bamboo plants can yield plenty of raw material while still maintaining a pretty much normal life cycle. After being cut, a bamboo forest can regenerate within a matter of a few short years. By contrast, a hardwood forest can take decades, even more than 100 years to go back to its original size after it gets logged.

Material Yield
A bamboo forest produces up to 25 times more usable building material for buying a thatched umbrella, or bamboo poles than a traditional hardwood forest. One bamboo plant with multiple shoots can yield 200 bamboo poles in over the course of five years. Compare this to a hardwood tree, which has to wait five years to even grow big enough to be cut down in a way that’s commercially viable.

A Healthier Atmosphere
Just one bamboo plant can produce up to 35% more oxygen than a whole handful hardwood trees, which is why bamboo farms are great for reforesting razed land. Bamboo, according to the World Wildlife Fund, also can store about 6.88 metric tons of carbon per year. That’s roughly 70% more than hardwood trees are able to store. This means that, when bamboo is turned into flooring and fencing material treated to prevent rot, the carbon it holds can be kept fixed for decades.
