Globally, over 14,000 animal species face a risk of extinction. The reasons for the near extinction include poaching, habitat loss, human-wildlife conflict, pollution, diseases, climate change, and low birth rates (IUCN, 2021). Some of the most endangered species include the Javan rhino, African elephants, black rhino, snow leopards, orangutans, the vaquita, Amur leopards, and the eastern lowland gorillas. With the appropriate conservation measure, endangered animals may increase over time.
Captive breeding and reintroduction are among the most effective conservation approaches. They involve capturing, breeding, and rearing endangered animals in wildlife reserves, zoos, or aquariums to help increase their numbers. After a significant number is raised, the animals can then be released back to their natural habitats. For example, in 1982, only 22 California condors existed in the wild; however, captive breeding increased the number to 425 in 2014 (Association of Zoos & Aquarium, n.d). Thus, when threats are reduced, the rare species can improve in numbers.
Habitat protection is critical in ensuring the safety of endangered animals. Protected areas where endangered species can be placed include nature reserves, national parks, and wildlife refuges. There are various marine reserves and protected areas that prohibit fishing, thus safeguarding the marine species. In this case, New Zealand has several marine reserves that protect sea turtles, aquatic mammals, and some fish species such as manta rays and white pointer sharks (Ministry for Primary Industries, n.d). Additionally, some laws and regulations safeguard wildlife at state, national, and global levels to prevent animal extinction. In this case, CITES or the Washington convention significantly regulates the global trade of wild animals. This treaty restricts and controls any trade involving endangered species to ensure they do not become extinct
In conclusion, human activity and climate change continually threaten some wild animals’ survival. Nonetheless, appropriate conservation methods such as captive breeding and habitat protection can ensure the continuous reproduction of these species. The enactment of state, national and global laws that safeguard wild animals also promotes the survival of these species. Human beings have a responsibility to ensure the protection of wild animals and their habitats.
Global warming is one of the biggest threats to animal and plant survival. The accumulation of greenhouse gases into the atmosphere, deforestation, and increased agricultural activities are major contributors to this phenomenon. The increased earth temperature associated with global warming has led to climate change resulting in several natural calamities. However, the threat of global warming can be reduced by using renewable energy, recycling, planting more trees, and lowering the emission of greenhouse gases.
Global warming has significant adverse impacts on human beings and the environment. The extreme heat associated with climate change increases complications from underlying respiratory and heart diseases such as renal failure and asthma and may cause other heat-related disorders. Global warming also increases the risk of storms and drought, affecting food supply, which may cause death to both humans and animals (Global Climate Change, 2021). It has also been linked to ocean acidification, increased ocean temperature, and rising sea levels. Such occurrences have led to the death of a significant number of marine life.
Rather than human actions, global warming may result from natural forces. Human activities such as deforestation, industrial processes, and agricultural activities have long been attributed to climate change. However, there are claims that complex gravitational interactions, particularly alterations in the earth’s orbit, torque, and axial tilt, may also influence climate change resulting in increased temperature (Neaves, 2017). Gradual shifts in the earth’s orbit combined with its axial tilt places the south and north poles more directly to the sun resulting in temperature extremes.
In conclusion, global warming has adverse effects on humans and nature. It exposes humans to heat-related diseases and increases complications of respiratory illnesses such as asthma. Climate change depletes vegetation causing food shortage and death to humans and animals. Similarly, it causes ocean warming and acidification, which destroys marine life. Although some natural forces such as shifts in the earth’s orbit and axis may trigger temperature changes, human activities are the greatest contributors to global warming.
