Plants were the first species to evolve on earth and they evolved in the water. They then spread to land. These plants allowed the first fish and later the first land animals to evolve. Plants have been evolving and diversifying for millions of years and are the basis of all life on earth.
Plants use a process called photosynthesis to feed themselves. They take in the light from sun and use it to turn carbon dioxide and water into sugars which the plant then uses as its food source giving the plant energy and life. The plant releases oxygen as a byproduct of this process.
There are an estimated 298,000 species of plant on earth, of which, only 215,644 have been described and cataloged. Within this broad group there are five groupings – flowering plants; conifers, cycads and allies; ferns and fern allies; mosses and liverworts; and water plants. Each species is then divided into families. Each family is then separated into Genus groupings.
Areas of growth –
Plants grow in all climates and all ecosystems. Each plant species is uniquely developed to survive in its particular climate and ecosystem. That survival can depend on other plants in the area, on animals, bugs, and fish, and even on humans.
Importance of plants –
Plants are important because they make up one third of our food supply and supply food to other species. Plants are our food source directly and indirectly; we eat them and the animals that we eat also eat them. They turn our carbon dioxide emissions into oxygen. On a smaller scale they provide beauty for us to see all around. They provide home to many of the smaller species on earth.
What is happening now? –
There are many things affecting the biodiversity of plants. Climate change, topsoil erosion, acidification in oceans and land, clearing forest land for farming, the death and disappearance of pollinators such as bees, and humanities monoculture farming industry are all large factors in the threat to biodiversity.
What will happen if we do nothing? What are the hot spots or key issues? What can we do? What can our community and or country do?
If we do nothing year by year biodiversity on earth will become less and less diverse. Whether it happens through extinction or destruction is unimportant. What matters is whether or not we will see it in time to stop it. Truthfully it is already too late to stop it all together, species extinction or endangerment is already happening. If we work together to make the world a better place we may not save all the currently endangered species but we can save some and even a few is better than none.
The key issues today are deforestation, pollution of air, water, and land, and the control exhibited by big corporations. All the other problems can be traced back to roots in one of these key issues. Admittedly it is hard for a single person to make big changes to the world but if each individual makes a few changes to their lives than overall there will be a positive impact. Families should get together and plant pesticide free gardens to help stop the disappearance of pollinators like bees. Individuals and communities can send letters to their elected officials and write and sign petitions. A big factor would be supporting innovation for items that are environmentally friendly and boycotting as much as possible the corporations that are trying to keep environmentally friendly bills and legislature out of the laws.
There are many beautiful species on Planet Earth.
What can you do?
– Explore Nature!!!
– Grow your own food in a garden!!!
– Plant native trees and seeds
– Write a letter to the president or prime minister, and tell him to preserve biodiversity.
– Learn more about the Earth, and its many beautiful species….

Bees – a small and often overlooked part of our lives
Bees are the basis of about 1/3 of our food supply. They are responsible for pollinating the flowers of our fruit plants; from bushes to trees. In 2006 Bees began disappearing, now in 2013 we have begun to point the figure at least one of the culprits – neonicotinoids. These strong pesticides are sprayed all over our farmed crops, such as corn, wheat, and soy. This is not however the only threat, as with any species, human land development has already killed of many wild bee species. Genetically modified plants may also be to blame since many have insecticides within their genetic structure. In an attempt to boost productivity humans artificially inseminate the queen bees leadingto a less diverse bee population. We can save the bees by banning pesticides that are known to cause their deaths and by allowing them to live as is natural to them, not boosting productivity for our benefit. In the end if we do not change bees will become extinct and with them the most natural way to pollinate our plants.

Silence of bees
In the winter of 2006, a strange phenomenon fell upon honeybee hives across the country. Without a trace, millions of bees vanished from their hives. A precious pollinator of fruits and vegetables, the disappearing bees left billions of dollars of crops at risk and threatened our food supply. The epidemic set researchers scrambling to discover why honeybees were dying in record numbers — and to stop the epidemic in its tracks before it spread further.
Silence of the Bees is the first in-depth look at the search to uncover what is killing the honeybee. The filmmakers of Bees take viewers around the world to the sites of fallen hives, to high-tech labs, where scientists race to uncover clues, and even deep inside honeybee colonies. Silence of the Bees is the story of a riveting, ongoing investigation to save honeybees from dying out. The film goes beyond the unsolved mystery to tell the story of the honeybee itself, its invaluable impact on our diets and takes a look at what’s at stake if honeybees disappear. Silence of the Bees explores the complex world of the honeybee in crisis and instills in viewers a sense of urgency to learn ways to help these extraordinary animal
