Itis unquestionable that many plant and animal species are losing their naturalhabitats and they are becoming extinct in nature. There are several causes ofthis universal issue, but measures could be taken to tackle the problem. Thiswill be proven by looking at some of the causes and effective solutions to theproblem.

Oneof direct causes should be mentioned that is indiscriminate logging worldwide.For example, in many countries the trees are being uprooted giving the way tolarge-scale farmland of rubber, coffee and tea plantations. As a result, thenatural habitat of wildlife has been affected significantly by thedeforestation, and been worsened by forest fires and poaching endangeredspecies.

Secondly,much of the human actions are responsible for the destruction of marine life. This,devastation is apparent when the industrial waste and nuclear waste is pumpedinto sea and oceans. This chemical waste kills the aquatic plants and animals,thus not long halting life cycle but also causing the decline of bio-diversity.

Thethird reason is the species invasion. Deep globalization has brought newspecies into a specific geographic area, which results in unintendedconsequences. They are exotic to the environment and can disrupt the ecologicalbalance of the native species. For instance, with no natural defense to the newinterlopers, many native species become the prey of these invasive species, andgo to the extinction gradually.

Thefirst-proposed solution is to encourage companies, organizations and peopleespecially ethnic to participate in planting trees and protecting forestthrough supporting interest rate for related activities such as buyingseedlings. Next to this solution, there is a necessity for the intervention ofgovernment to enact strict laws, regulations and punishments for the companiesresponsible for the runoff of chemical pollutants into the water and mountains.Moreover, an international agreement between developing and industrializenations should early be adopted to tighten the consumption of wildlife andillegal-sourced wood products.

Inconclusion, it has been shown that plants and animals are on its last leg.Thus, it is predicted that the government should make some stricter rules in anattempt to safeguard plants and animals.(356)
