人类可以对环境的积极变化产生影响。此外，只有人类才能对环境产生积极的影响。环境得以改善的方法之一是圈养繁殖和释放濒危物种和动物。灭绝的动物可以在受保护的环境中繁殖。当濒临灭绝的动物受到保护并不断繁殖时，它们就被重新引入了世界。另一个影响包括清除入侵物种。由于这些原因，一些植物和动物可以被引进到新的地区。这可能导致当地植物和动物以及生态系统中存在了数千年的部分弯曲。其中一个例子是橡胶树，它被用来支持其他植物(Nyssen et al, 2014)。保护当地物种是改善环境的另一种方法。由于非法偷猎，印度虎一直受到威胁。无论是行动缓慢的动物还是浅水区的海牛都受到了威胁。在澳大利亚，森林大火的控制是自发地开始的，它导致森林的枯竭和生活在其中的动物的死亡。人类的努力在一定程度上帮助了破坏。定期清理水道可以防止河岸泛滥，保护大量的生态系统。另一种改善环境的方法是寻找可再生能源。通过使用生物燃料，石油储量的快速枯竭将减少对石油的依赖。当地的电力需求可以通过风力涡轮机和太阳能发电厂来维持。技术可以用来减少污染。这可能包括使用一些纳米技术过滤系统，这些系统用于净化水、吸水性材料和以油为基础的消化细菌培养物。此外，与森林砍伐有关的努力应由重新造林来满足，其中包括耕作、放牧和人类定居的过程。
The human beings can have the impact of the positive change in the environment. Also, it is the human beings only who can have the positive impact on the environment. One of the ways by which the environment can get better is by the captive breeding and the release of the endangered species and animals. The extinct animals can breed in a protected environment. When the animals who are getting on the verge of being extinct will be protected and breed again and again, they have been reintroduced in the world. Another impact includes the removal of invasive species. Some of the plants and animals can be introduced in the new areas which are thriving in those reasons. This can lead to the winding of the indigenous plants and animals and the part of the ecosystems which are there for a thousands of years. One of the examples is the gum trees, which are being used to support the other plants (Nyssen et al, 2014). Protection of the native species is another method through which the environment can be improved. The Indian tiger has been under threat because of the illegal poaching. Be it the slow moving animals or the manatees which are shallow-water bodies are under threat. Control of wildfires is one such much that is spontaneously started in Australia and have to the depletion of forests and the killing of animals who live in them. The efforts of human beings help the damage to some extent. Periodic cleaning of the waterways leads to the prevention of the flooding of banks and the protection of a large number of ecosystems. Another method for betterment of environment is by finding the renewable sources of energy. By the use of bio-fuels there will be the reduction of dependence of the fast depletion of the reserves of oil. The local electricity needs can be maintained by the wind turbines and the solar plants. Technology can be used for the reduction of pollution. This may include the use of a number of nanotechnology filtration systems which are used for the purification of waters, absorbent materials, and the oil based digesting bacterial cultures. Further, the efforts related to the deforestation should be met by the reforestation which includes the processes for cultivation, grazing and for human settlement.
