Bees play a vital role in the world. Unfortunately, bees are dying by the second.
The main purpose of bees is to make honey. Honey, shockingly, does not exist for human consumption, it is essential to the insects. Honeybees store honey in their hives (蜂巢) in order for the bees to have energy for their flight muscles and for heating the hive during the winter period. They collect pollen (花粉) which supplies protein for young bees to grow.
According to Honey, com, the increased production and quality of agricultural crops as a result of honey bee pollination is valued more than $14.6 billion per year. These insects are responsible for over 70 of the fruits and vegetables we eat today, including apples, grapes, coffee, beans, and broccoli.
So if they are so valuable to agriculture, why do they keep dying off? A key suspect seems to be pesticides (农药). Honeybees who are exposed to pesticides result in the damage to their neurological (神经的) functions, specifically memory or behavior. And that’s why the majority of worker bees disappear and leave behind a queen, plenty of food and a few nurse bees to care for the remaining immature bees and the queen. There are several other causes to the decline of bees, including the destruction of natural habitat, like woodlands, forests, and other habitats for bees. Climate change is also a factor in the decline of the wild bee population.
Actually, there are a variety of methods to help the bee population grow. One way is to start your own organic garden by planting bee-friendly plants. Pesticides are used in both industrial practices and even in your home, so it is best to find organic seeds and weed killers.
