How we can reduce the effects of environmental problems, and keep our environment more sustainable? This involves three aspects: Biological, Physical, and Human.
The Biological aspect focuses on the importance of biodiversity and the actions we can take to conserve basic ecosystem functions. For example: introducing some key species like the genetically engineered honey bee to protect the agroecosystems or to eradicate diseases like introducing a particular type of mosquito to kill another type of mosquito.
The Physical aspect consists of clean air and water resources. They are crucial to maintaining biodiversity and our basic life-support systems. It deals with methods for reducing air and water pollution like cleaning and keeping our lakes and rivers clean while imposing lawful measures to prevent people from further polluting.
The Human aspect investigates how development can be sustainable under the current pressures at local, regional, and global scales. Examples include water reuse, green building and solar panels, and environmentally friendly technologies. For instance, members of the Cope 21 are engaged in reducing their carbon footprint whilst the World Bank is making huge funds available to member countries in order to invest in sustainable development.
