The sky is pale blue in higher altitudes while it is deeper blue in lower altitudes. This is because there is more air molecule closer to earth surface (as a result of higher air pressure) than higher altitudes. The air molecules are responsible for scattering of sunlight hence giving the sky its blue hue. The more the air molecules the more the scattering.
To keep the species from dying off.
Answer:
Aquaculture has been considered as an option to cope with the world food demand. However, criticisms have arisen around aquaculture, most of them related to the destruction of ecosystems such as mangrove forest to construct aquaculture farms, as well as the environmental impacts of the effluents on the receiving ecosystems. The inherent benefits of aquaculture such as massive food production and economical profits have led the scientific community to seek for diverse strategies to minimize the negative impacts, rather than just prohibiting the activity. Aquaculture is a possible panacea, but at present is also responsible for diverse problems related with the environmental health; however the new strategies proposed during the last decade have proven that it is possible to achieve a sustainable aquaculture, but such strategies should be supported and proclaimed by the different federal environmental agencies from all countries. Additionally there is an urgent need to improve legislation and regulation for aquaculture. Only under such scenario, aquaculture will be a sustainable practice.

Explanation:
The rain forest zone contains an abundance of plant species available for pharmaceutical research and attempt at the synthesis of new drug compounds. The abundance of rainfall helps these many plant species to thrive and are available for use in the development of new drugs.
