Answer

Chosen Ecosystem – Aquatic Ecosystem The major consequences of the threats on aquatic ecosystem includes destruction of habitats, exotic species, and the change in climate (Ch. 1 Introduction - Biology 2e | OpenStax, n.d.). A prominent example of the threatened aquatic ecosystem due to human intervention is of Western Atlantic Cod Fishery which resulted in the collapse of the fish population from their natural habitat (Hamilton et al., 2004). Earlier this fishery was considered productive almost for 400 years and was one of the major sources of daily dietary requirement in the regions of Western Atlanta. It was in 1980s that the modern factory trawlers were introduced and the pressure on the fishery was increased (Commercial Fishing Causing Collapse - Wild Earth News & Facts, n.d.). These two factors collectively made the entire fishery practice an unsustainable approach. The underlying cause of this approach was found to be the economical and the political factors(Why Fisheries Collapse and What to Do about It on JSTOR, n.d.). Fishery comes into the common property which means that if the water body is shared between two or more geographical region people from all the regions would have access to it and they can use this water body in a way they need. This makes the fishery practice susceptible to a tragedy called “Tragedy of Common” which results in the overexploitation of these water bodies and thus making aquatic ecosystem disturbed (Atlantic Cod And The Human “Tragedy Of The Commons” | Cognoscenti, n.d.). For instance, whales are the slow growing population and are at risk of extinction through hunting. This scenario is a result of the economic force being exerted by the inhabiting population. Whales killed for bush meet is traditional practice in the African countries, but the recent commercialization of the hunting practices made the bush meet available in the local grocery stores too which ultimately increased the harvest rate (Ripple et al., 2016). The growing human population has increased the protein requirement and thus causes the many a fold increment on the hunting practices of the aquatic animals. The species threatened for the bush meet are commonly found from Congo Basin.

a). Choose a specific ecosystem (eg a coral reef, a desert, a rainforest) and briefly describe a situation where human intervention has significantly altered it (either for the better or the worse). Remember to describe the ecosystem both before and after the changes and explain the factors that have caused the transformation (examples would include logging companies clearing large areas of forest or the introduction of a treatment plant that reduced the amount of raw sewage piped into the sea).

In order to target a specific region of genomic DNA with CRISPR, researchers must include a guide RNA containing a 20-basepair (bp) long spacer sequence that matches the DNA sequence at the target site. One of the possible risks of genetic engineering methods is "off-target" editing, which occurs when a guide RNA matches a part of the genome other than the intended target site. (i) How many possible guide RNA sequences are there? (ii) Estimate probability that a single site in the human genome matches a random 20-bp spacer. State all your assumptions. (iii) After infection, HIV converts its RNA genome into DNA and inserts itself into the human genome. Imagine you have designed a 20-bp spacer to target and deactivate part of the HIV DNA sequence. Based on the previous answer, estimate the probability that this sequence will have at least one off-target match somewhere in the human X chromosome, which is 300 000 bp long (counting both strands). Note: when P is very small (close to 0), (1-P)^n is approximately equal to (1-nP). (iv) What would be the probability of an off-target site appearing somewhere in the entire human genome (6 billion pairs counting both strands)?

b). Discuss how far you believe human beings should go to protect current ecological systems (if at all) and whether you think there is ever a time when natural ecology should be sacrificed for human needs.
