Summary Introduction
To determine:
Welwitschia plant has a large number of closed stomata which are beneficial to the desert plant.
Introduction:
Welwitschia mirabilis is a desert plant which is mostly found in the Namib and Mossamedes deserts in Africa. The plant is often described as 'bizarre', 'weird', or 'unlike any known plant on earth’. Rainfall and moisture from fog are the two essential conditions for the survival of this plant. The average rainfall in Africa is about 2.5 centimeters per year. This plant can live upto 15,000 years approximately. Welwitschia has a large number of stomata (22,000 /cm3) which remain mostly closed. Stomata are responsible for the process of transpiration (loss of water in the plant).

Using information from the primary literature (several references have been provided as a starting point below) please answer the following question: Based on your review of the literature on rewilding, what are the major scientific pros and cons for rewilding?
Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions.
Details:
You must enumerate at least two pros and at least two cons.
Your answer should be no more than 500 well-chosen words, excluding references. Think carefully about how best to organize and structure your answer. Aim for high information density: say a lot, but say it succinctly. Recall Nietzche’s…
