1 . How to grow tomatoes?

Given the proper climatic conditions, you can grow tomatoes nearly anywhere. Before you grow tomatoes, check if your area has the right climatic conditions for this purpose.     1     And if it doesn’t, just give up this idea.

    2    One is to grow them from seed and the other is to grow them from the plants. The seeds usually take six to eight weeks to grow. If you don’t know how to grow tomatoes from seed, you can consider buying the plants directly. Many of these plants can be found at most garden centers.

Tomatoes don’t grow well in cool conditions.     3     Tomatoes require areas with full sun and should have enough protection from strong winds as well, that’s more, they require a lot of water; therefore, you had better water your tomato plants regularly.    4    

Check tomato plants daily for any ripe produce. Picking often helps more to grow. Once the end of growing season is coming, it’s helpful to remove any flowers as well.     5    If you still have a lot of green tomatoes during this time, go ahead and pick them. These can be stored in a warm area up to four weeks, and then they will turn red.

A．It's not that difficult to grow tomatoes.

2 . On a sunny but bitterly cold February day, a line of small children snaked their way from Dale to Dale Fort on the Haverfordwest estuary. They were the last of more than 2,000 volunteers who over the last year have collected, stored and put seagrass seeds into little bags, ready for planting. These seagrass seeds were soon to join others on the seafloor a few hundred metres off-shore from Dale to recover two hectares of seagrass meadow (草甸). This recovery is the latest attempt to change a century of destruction.

In the UK, we can only estimate the loss but in Denmark, seagrass records dating back to the 1880s give a very serious and accurate picture. At the turn of the last century, fishing was vital to the Danish economy. It was known then that seagrass meadows were a vital habitat for young sea fish and so in 1908 botanist Carl Ostenfeld was asked to study the seagrasses, then found in all the estuaries and entrance of Denmark. That study provided a clear standard against which to measure the loss of seagrass in Denmark, a loss that currently stands at 95 percent.

Why does this matter? Seagrass not only provide a nurturing habitat for fish but also stabilises the shore and absorbs energy, reducing the impact of storms. Boat anchors (船锚) are one cause of damage to seagrass; seashore development another. But the main cause is river water pollution, particularly nutrients from fertiliser and dirty water. These excess nutrients cause algal (藻类) growth that blankets the seagrass, cutting out light, and then later, when it dies off and rots, removes all oxygen.

One of the important messages is, if you stop killing sea life and protect it, then it does come back. We can turn the oceans around and we know it makes sense economically, for human health and, of course, for the environment.
