Biodiversity essay writing Canada

Some researchers believe that there are fewer or more levels than these, but the consensus is that three levels is a good number to work with. For example, a person may believe that every species has an intrinsic right to live but may also be excited about prospects for finding new medications from the earths plant and animal species. Ask them to explain why they think its important for these animals to be protected.

Monocultures are also unable to deal well with changing conditions. Genetic diversity is the variety present at the level of genes. In communities, it can increase with the diversity of species.

Write essays in which they explain what they feel are the most compelling reasons for preserving biodiversity and also describe the arguments they think would be most likely to convince the general public that biodiversity should be preserved. How much it increases depends not only on the number of species, but also on how closely related the species are. A lake may have a very sharp boundary between it and the deciduous forest it is in, but the deciduous forest will shift much more gradually to grasslands or to a coniferous forest.

Five major arguments are (biodiversity can help people make money or keep people from losing money) (people love outdoor activities like fishing and backpacking, which would not be possible if ecosystems were destroyed) (biodiversity can help people find better cures for illnesses) (if biodiversity is protected, indigenous people can continue to live in their native lands) and (biodiversity should be preserved for its own sake animals and plants have a right to live people rely on wild places and creatures for spiritual fulfillment). Within species, genetic diversity often increases with environmental variability, which can be expected. If the environment didnt change, then the small number of genes that had an advantage in that unchanging environment would spread at the cost of the others, causing a drop in genetic diversity.

Three class periods (it may be reduced to two periods if students write the essays at home) people take different approaches when making the case for preserving biodiversity. This is the least-understood level of the three described here due to the complexity of the interactions. Which of the five pro-biodiversity arguments do they think would be the most productive and convincing, and why? They can suggest that the organization use all five arguments, just one, or a few.

Biodiversity studies typically focus on species. If they are so specialized, this specialization will lead to little genetic diversity within any of the species. Have each student write a two-paragraph essay about preserving biodiversity. These closely-related species will contribute to genetic diversity in the community less than more remotely-related species ( an increase in species diversity can also affect the genetic diversity, and do so differently at different levels. The second paragraph should explain which of the arguments they read about on the internet seems the most likely to convince people that biodiversity should be preserved.

    Genetic diversity can be measured at many different levels, including population, species, community, and biome. Three class periods (it may be reduced to two periods if students write the essays at home) people take different approaches when making the case for preserving biodiversity. Divide the class into groups of about three students each. You can pose the following questions as guidelines for writing the paragraphs youve learned about several different reasons why people believe biodiversity should be preserved. Most studies, either theoretical or experimental, focus on the species level, as it is the easiest to work on both conceptually and in practice.

    If the environment often changes, different genes will have an advantage at different times or places. The term ecosystem here represents all levels greater than species associations, communities, ecosystems, and the like. Tell them that many people who believe biodiversity should be preserved will use more than one of these arguments to make his or her point. Researchers generally accept three levels of biodiversity genetic, species, and ecosystem. Why should ecosystems be kept healthy, with every member of the ecosystem protected? Groups should list all their ideas.

    Some researchers believe that there are fewer or more levels than these, but the consensus is that three levels is a good number to work with. Each species can be considered to have a particular role in the ecosystem, so the addition or loss of single species may have consequences for the system as a whole. Ask students if theyve identified any of these types of arguments in their lists. Canadas public lands are the home of several rare plant and animal species, so naturally preserving public lands is one the issues on the bio-diversity front. A lake may have a very sharp boundary between it and the deciduous forest it is in, but the deciduous forest will shift much more gradually to grasslands or to a coniferous forest. If there are many species, the genetic diversity at that level will be larger than when there are fewer species. Less diversity leads to uniformity, which is a problem in the long term, as it is unlikely that any individual in the population would be able to adapt to changing conditions. In communities, it can increase with the diversity of species. Which of the five pro-biodiversity arguments do they think would be the most productive and convincing, and why? They can suggest that the organization use all five arguments, just one, or a few. Species are also easier to conceptualize and have been the basis of much of the evolutionary and ecological research that biodiversity draws on.
