Second probable method is beekeepers’ usage of purple loosestrifes to get more nectar. By beekeepers and early settlers, purple loosestrifes were introduced to Canada. Purple loosestrifes reduce biodiversity by degrading natural habitats such as wetlands and replaces native vegetation rapidly. They blocks native plants to grow by forming dense mats with their roots. If native vegetation being replaced with purple loosestrifes, it will impact animals, too.
There are some people who believe that the United States' strictly forced endangered species laws seriously hamper our economy. I on the other hand must disagree. The endangered species laws were created for an important reason: to protect our earth's biological diversity. Whenever humanity interferes with the ecosystem for the purpose of economic growth it tears it apart piece by piece. It is for reasons like these we must have such tough laws, as in the Endangered Species Act.
If we continue to turn a blind eye, well, we all know how that story ends. The only hope is that we alert the authorities as to how we feel about this issue and make sure that they put our ideas into action against these genetic engineering companies. Otherwise we may as well forget the years that we’ve spent trying to save our natural resources. Works Cited Hosansky, David. “Biotech Foods.” The CQ Researcher Online 11.12 (2001).
Tomatoes varieties are either hybrid or heirloom varieties. Hybrid tomato seed is produced by the cross pollination of two separate parent lines. (Get in depth about how gene selection works, good opportunity for good scientific research) Hybrid tomatoes generally have more uniform growth, disease resistance and a longer harvest interval, which are characteristics desirable for those marketing their fruit. Heirloom tomatoes have been selected by humans for many years for their flavor profile and their ability to thrive in a specific climate or territory. Many amateur gardeners save seeds of these varieties along with large commercial seed producers.
On the contrary, people around the world don’t understand the fact that this environmental issues are actually cause by our own wrong doings that leads the world to face the current environmental crisis. It is important that we take action as a consideration for the future of mother earth and for future generation. As children of our mother nature we should protect us country as much as possible so that we could avoid environmental issues. The first global environmental problem is haze this is caused by burning down forest. As we all know that green forest is important because it creates photosynthesis for flora and fauna for human begin.

Oil spills, pollution and soil degradation has caused many of the species in that region to lose their habitats. Hopefully with this plan I will be able to not only reduce threatened species but also preserve biodiversity in each province, and that would benefit Canada as a whole. As you can see biodiversity loss is a very pressing issue and should be prioritized by the prime minister.
Biodiversity, the “complex web that sustains life on this planet” (Austin, et al., p. 5), is vital for our survival as humans (Cuthbert p. 74). Any loss of biodiversity affects the entire ecosystem and all organisms within it (Fetene et al., p. 52). In the quest to house the ever-expanding human population, we must also consider habitat conservation and seek to preserve the rich biodiversity found in the Fraser Valley that supports and enriches our lives. Perhaps the most devastating disregard of the Fraser Valley’s biodiversity was the draining of Sumas Lake to create farmland, resulting in the loss of habitat and the extirpation of endemic species. As it was originally intended to be, the Fraser Valley was a “perhaps unparalleled ecosystem” (Rosenau, p. 55), with bountiful wetlands and remarkable biodiversity.
We must find more ways to cut back on the use of chemical herbicides and change to biological weed control methods. Foreign plants which turn into weeds are continuously being introduced to Australia both accidentally and intentionally. They can cause extreme damage to Australia’s environment, as they threaten the survival of many native plants. They are successful in growing as they - usually grow faster than native plants competing for nutrients, water, space etc, they survive better as they do not have the pests and diseases that would normally control them in their natural habitats, they take over the native plants that the native animals use for shelter, food and nesting. The Cobblers peg (Bidens pilosa) also known as farmers friend, Spanish needle and beggars tick was introduced from South America and has become a weed in Australia.

The production of high quality planting material of exotic nature propagated from vegetative parts through tissue culture has created new opportunities in global trading. The exotic plants are advantageous for farmers;growers; nursery owners & rural employment. As exotic plants are restricted to their natural environment; the main benefit of tissue culture technology lies on production of high quality & uniform planting material that can be multiplied on a year round basis. The plant selected for such purpose is Stevia rabuadiana Bertoni.
Farmers prune trees to 1.5-2 metres and clear vegetation. The trees that remain provide fruit, fuelwood, shade for crops and assist water movement in the soil (Food and Agriculture Organization of the United Nations, n.d.). According to (Castra et al. 2009): It is originating from southwestern Honduras but has spread to other regions in Honduras, Nicaragua and Guatemala. QSMAS focus on smallholder farmers minimizing land degradation while simultaneously providing an easily adoptable method to the current slash and burn practices.
