Many solutions have been attempted to be created over time, though there are still many pros and cons for each of them. Biodiversity provides clean water, oxygen, medicine and the food we eat, which all are essential for the health of human beings. According to panda.org, then if the biodiversity decreases at some of the most biodiverse places on the earth, such as the Amazon, then it most likely will have negative effects on the entire planet. Biodiversity ensures a natural living form for all living organisms and it boosts a ecosystem’s productivity where each species, no matter size all have an important role. Healthy ecosystems can better overcome and recover from challenges.
They also help water move from the soil to the atmosphere through a process called transpiration. Plants not only supply us with food, but with other provisions such as wood products, fibers, oils, resins, coal, and petroleum. They also provide us with raw material needed to make shelter, clothing, medicines, and fuels. It’s also a fact that one quarter of the medicines we use are derived from plants; and that 4 out of 5 people in this world rely on plants for primary health care. Importance of Plants Plants are everywhere.
Lareina Chen Mr. Hayward 9A January 11th, 2017 Genetic Engineering Essay Genetic engineering is a powerful and dangerous technology. Sometimes called genetic modification, genetic engineering is the process of altering the DNA in an organism’s genome. Editing the sequence of nucleotides can sometimes lead to extreme harmful effects on the human race, while on the other hand generates huge benefits for society. While talking about Genetic engineering, it is carried out by CRISPR. CRISPR stands for “clustered regularly interspaced short palindromic repeats.” It can quickly twist most of the genes in any plant or animal.
What can we do if we ourselves may be the cause for all this loss? Shocker!? Yes human have a very large part in the extinction of species in both plant and animals. We do it for our needs but little do we realize that one day it’s all going to come crashing down for us because of our imbecile mistakes. We must learn to preserve the environment we have today for the future generations to come without compromising the needs of our current population, in simple words it’s called learning to sustain what is left of biodiversity.
However, now days where globalization intercepts species have begun to dissolve at a very alarming and devastating rate. When a species dissolve, important components of our web of life dissolve as well, constantly in ways not well understood by everybody. “Scientists appraise that the mislaying of species
They are still found today everywhere and have successfully evolved to still survive. Bacteria is where all the other kingdoms branch off from. Though Bacteria and Archaea are both prokaryotes, their genes are less than half related. Bacteria have its pros and cons for life on earth as some of them are good for the environment such as, food production, medicines, pest control, and etc. However, the cons are they can cause diseases, pathogenic, and etc.
To date, much effort has been made to understand key factors controlling salinity stress. The genetic determinants and hormonal signalling pathways that underlie salinity survival strategies still need to be identified. A genomics approach can greatly help with the identification of genes, and therefore potential gene products, that are involved in the plant salinity response. Functional genomics also provide a new opportunity by which to gain molecular and physiological knowledge that could be used to improve the salinity tolerance of plants relevant to crop production and environmental sustainability (Munns and Tester 2008 ). In fact, the most widely used plant model plant, Arabidopsis, has been used to characterise the important
What is biodiversity? Some may say it is just merely a number of species within an ecosystem. However this is not the case, as majority aspects of our lives solely depend on biodiversity. Water, food and air are produced directly by different species and the quality of these resources depend on other species activities. According to the convention of biological diversity "Biological diversity means the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems” The important question however, is can we put a value on biodiversity?
Medicinal plants have been practiced by almost every culture as a source of medicine since the origin of life. Literature from different field studies in the last few decades revealed that traditional people, local communities, indigenous knowledge around the world withhold the prime local plant knowledge, practically utilized in their daily practices and transmit their knowledge orally to others (Martin, 2004) (Lulekal etal., 2008). The livelihood for human populations is totally based on natural resources and biological biodiversity. Therefore, human beings have a great influence on local vegetation directly or indirectly (Delcourt and Delcourt, 1998). Ethnobotany is a flourished discipline of science which covers all type of interaction and relationship between plants and people (Afolayan and Jimoh, 2008; Silva et al., 2011).
Land use changes, such as landscape modification and habitat fragmentation, are believed to have a negative impact on almost all taxonomic groups (Fisher & Lindenmayer, 2007). Invasive species, usually introduced by human activity, outcompete or consume native species (Chapin et al., 2000). Climate change will alter species distributions, trophic networks and ecosystem functioning (Bellard et al., 2012).
