Vegetables and fruits combined make up over 50% of what we eat or need to eat every day to maintain a healthy body. In the past few years, many farmers and gardeners had used greenhouses for keeping their crops alive during the harsh winter. Greenhouses became the most popular idea for farming in the winter. However, with a new idea of exploiting the power of magnifying glass, we might be able to use them to rescue the plants from winters' cold climate.
During the winter, plants die because of many reasons. Low temperature freezes water in plant cells, causing the cells to be damaged. This is a common explanation for why most small plants wither in the winter. In addition, hardy plants tend to die due to prolonged dry soil. The roots cannot take water from the soil and as a result, the tree dying from lack of moisture.
Another explanation is the lack of sunlight during winter. Plants use sunlight along with other natural resources like water and carbon dioxide to create their own food called glucose. This process, as we all know, is called photosynthesis. Lack of sunlight in the winter prohibits the plant to harvest the energy it needs therefore resulting an unhealthy plant.

Using magnifying glasses, we can allow plants to receive the sunlight they need in order to survive. Normally, seeds would burn if this method was used, however, the cold will be able to keep the seed from burning due to low temperature. Since light intensity is one of the major factors that influence the rate of photosynthesis, it is reasonable to claim that using magnifying glass will allow plants to grow during the winter when there are hardly any sunlight. When he visited the Solar
Furnace Research Facility in Southern France, Jem Stansfield stated:
I’ve never seen anything set light to wood that quickly… There’s nothing on Earth that could withstand the temperature right in the middle of that. Just two square meters of sun shine can melt steel pretty easily; I’d love to try welding stuff with sun shine. Despite having trouble of being 93 billion miles away, the power of the sun can even melt rocks.
As you can see from the quote above, magnifying glass focusing ability can be quite powerful if there is a sufficient amount of sunlight. This is also why this experiment should be done in the winter so the focused sun beam won't disintegrate the tomato seed when it's suppose to aid in the photosynthesis process.

A man once tested the sunlight power by using the TV screen stated, "When it came into contact with the light, the wood instantly set on fire." The picture on the right, again, shows the amazing power of the focused light. That black bar of wood instantly caught on fire after it was in the "burning" zone.
