1. OK, let's move on to the late 19th century when a great deal of changes were taking place.
2. Now, first of all, I wanted to give you some background information.
3. So, let's have a look at some possible reasons for this.
4. And finally, I’d like to talk about some future projects.
5. So, what conclusions did we reach?
6. I’ll begin by explaining what this machine can do.

After gathering all of our data, we looked at the results. We realize that the number of frogs in this area had actually increased over the last 10 years rather than declined.

4

A: so, what does that all show?

B: well, I think we can deduce from this that all the development in this area should be halted until the animals have only been safely removed.

In today’s lecture, I’m going to talk about a part of that plans have played in our history, something more of us probably never gave any thought to. Flowers begin changing the way the world looked almost as soon as they appeared on earth around 130 million years ago. That’s relatively recent in geologic time - if all Earth’s history were compressed into an hour, flowering plants would exist for only the last 90 seconds. Without those flowering plants, it’s likely we wouldn’t be here. They are fundamental to our existence, forming a vital part of our food supplies.

If we look further on in time, to the year 2737 BC, we arrive at the discovery of tea by Chinese emperor, when a leaf fell into a cup of hot water. This discovery eventually played a very important part in the history of China, the USA and the UK. For Britain, where demand for tea was high, there were financial implications when a Chinese emperor declared that it could only be bought with silver, which day were than forced to find overseas.

A second influential planned in March around 202 BC in the form of the white memory. It became extremely sought after and it remain so until 220 a day because white mulberries provide food for the worm that creates silk. This luxurious material was responsible for establishing extremely valuable trade routes. And it was along these same routes that different religions made a way around the world. But, unfortunately, they also caused the spread of previously unknown diseases, as well as weapons of war such as gunpowder.

Finally, moving into more recent history, we come to the 16th century and a potato. It originated in central America but it was the Spanish who introduced it to the European diet. There, it quickly became popular because not only did it cause little to grow, but it was also a food source that was rich in vitamins. So much so that it arrival has been credited with ridding Britain of a disease known as scurvy. However, it is perhaps more famous now for the potato famine’s of the mid-1800s in Ireland. The Irish people were so dependent on the crop that its widespread failure over this period caused the deaths of over a million people and the emigration of a further million to mainland Britain, Canada and the US.
